Muiron Islands snorkel adventure

I’ve been lucky enough to have swum with whale sharks on a couple previous visits to the 604,500ha World Heritage-listed Ningaloo Coast, so today I’m checking out another area highlight: the underwater world of the Muiron Islands (North Muiron and South Muiron), located nine nautical miles north-northeast of Exmouth.

It’s early May, whale shark season here in Exmouth, Western Australia, but today’s underwater adventure doesn’t involve swimming frantically alongside the planet’s biggest fish, trying to keep up with its effortless-looking movement.

Muiron Islands

Where is the Muiron Islands?

The Muiron Islands is a 28,600ha marine area 15km north of North West Cape. 

It’s a popular spot for diving (you can join a diving safari from Exmouth). 

There’s a deep-water channel between South and North Muiron islands while a smaller island, Sunday Island, is to the east.

Popular diving spots in the Muiron Islands

The Cod Spot

The Cod Spot is probably the most impressive dive near Exmouth. The limestone reef is home to golden cardinalfish, giant potato cods, emperor fish and manta rays.

The Spit

The Spit has several swim-throughs along a ledge, where tiny baitfish, grey nurse sharks and turtles can be spotted. It’s a fantastic spot for drift diving over colourful coral and sponges.

Keyhole Plate

Shaped like a keyhole, this site on the western side of south Muiron Island has overhangs brimming with glass fish and an amazing array of soft corals.

Heading to the Muiron Islands

The speedboat ride between the marina and our destination, off the western side of South Muiron, takes about an hour and is bumpy at times.

I remain glued to my seat, thankful for the prescription-level seasickness tablets I ingested earlier (which are only partially working).

Waters are calmer once we reach the shelter of the islands, but I’m still glad that snorkelers get to abandon the boat and embrace the 26-degree Centigrade water first, while the scuba divers are still gearing up.

Snorkeling Muiron Island

Just yesterday, I visited a couple of Ningaloo Reef sites near Coral Bay, about an hour and a half south of Exmouth.

There, I encountered a beautiful, golden brown reef landscape.

Comparatively, the deeper corals at this South Muiron site sing with colour.

Muiron Islands snorkelling

As I follow my guide north, pale pink, lavender, peach, and yellow hard corals stretch out over the depths, 10 to 14 metres below.

Freediving down for a better look, a world of varied, abundant fish dance before my camera: angelfish, parrotfish, butterflyfish, trumpetfish, wrasse, and many more.

Changing course and swimming along the reef’s edge, we soon spot a green turtle resting under some corals.

The depths on this initial hour-long snorkel make me think this part of the Muiron Islands is better suited for scuba diving, particularly since not all of the snorkelers are free diving.

However, our second snorkel, at another spot off South Muiron, takes us to shallower waters, where the corals are only two to three metres below the surface.

We glimpse an octopus and reef sharks and come eye to eye with a hawksbill turtle swimming alongside a school of fish.

Our time observing this turtle is brief, though, as it soon disappears into a heavenly cloud of yellow convict surgeonfish.

Unfortunately, a building swell keeps us from moving to the island’s eastern side for our final snorkel. Instead, we remain at our current anchorage and drift south.

It’s not the most impressive snorkel of the day, but the waters are reasonably shallow, and we still see plenty of fish, a couple turtles, and perhaps thousands of convict surgeonfish, feeding with fervour on the corals below.

Does snorkelling the Muiron Islands beat the thrill of a whale shark swim?

Of course not.

But the pristine underwater landscape and abundant marine life make this a rewarding choice for another day.
